Description

Technical Field

[0001] This utility model belongs to the field of product quality inspection technology, and in particular relates to a quality inspection device for mechanical parts. Background Technology

[0002] Mechanical parts, also known as mechanical components, are the basic building blocks of machinery. They are inseparable individual parts that make up machines. The quality of mechanical parts has a crucial impact on the quality of mechanical equipment, affecting its operational stability and service life. Therefore, during the production and processing of mechanical parts, it is necessary to conduct sampling inspections to ensure their quality.

[0003] Research revealed that most current market methods for testing the strength of mechanical parts involve applying high pressure. However, these testing devices directly apply pressure to the parts without proper protection. When lower-quality parts break under pressure, high-speed flying fragments can easily cause injury, posing a serious safety hazard. Therefore, there is an urgent need to improve existing mechanical parts quality inspection devices and provide a new type of mechanical parts quality inspection device. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a mechanical parts quality inspection device that is reasonably designed, simple in structure, facilitates the centered and stable clamping of parts, and has good protective effects, thereby solving the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A mechanical parts quality inspection device includes a worktable, a servo motor, a hydraulic rod, a pressure sensor, a controller, and a pressure data display. A protective cover is fixedly mounted on the upper surface of the worktable. A servo motor for driving a clamping assembly is fixedly mounted on the right side wall of the worktable. The clamping assembly is located in the middle of the worktable and inside the protective cover. A sealing assembly for enhanced protection is installed on the inner rear end of the protective cover. A fixing tube is fixedly mounted at the center of the inner top wall of the protective cover. A hydraulic rod is fixedly mounted at the center of the top top of the protective cover. A pressure block is fixedly connected to the telescopic end of the hydraulic rod via a pressure sensor. Horizontal columns for driving the sealing assembly are symmetrically fixed to the outer upper wall of the pressure block. A controller and a pressure data display are fixedly mounted on the top of the protective cover, located on opposite sides of the hydraulic rod.

[0006] In a preferred embodiment, a reinforced glass panel is embedded and fixed at the front end of the protective cover. The reinforced glass panel is transparent, and the interior of the workbench is provided with symmetrical grooves.

[0007] In a preferred embodiment, the clamping assembly includes a bidirectional lead screw, movable rods, and clamping rods. The bidirectional lead screw is rotatably mounted in the middle of the worktable, and its right end is fixedly connected to the output shaft of the servo motor. The bottom of the vertical sections of the two movable rods are engaged and slidably located in the slide grooves, and are threaded onto the outside of the threaded section of the bidirectional lead screw. The horizontal sections of the two movable rods are each fixed with a clamping rod at their closest points.

[0008] In a preferred embodiment, the two reverse threaded sections of the bidirectional lead screw are located within the range of the two grooves, respectively.

[0009] In a preferred embodiment, the sealing assembly includes mounting rings, brackets, and sealing doors. Both mounting rings are bearing sleeved on the outside of the fixed tube and arranged vertically. The outer walls of the two mounting rings are symmetrically fixed with staggered brackets. The other ends of the two brackets are respectively fixedly connected to the two sealing doors. The two sealing doors are respectively movably located inside the left and right ends of the protective cover, and the centers of the three coincide with each other.

[0010] In a preferred embodiment, when the two sealing doors are closed, they form a closed structure with the protective cover. One side of each of the two sealing doors slides against the inner wall of the protective cover, and the other side surface of each of the two sealing doors is provided with a guide groove.

[0011] In a preferred embodiment, the ends of the two horizontal columns away from the pressure block are respectively guided to slide in guide grooves on the surfaces of the two sealing gates. The guide grooves include an inclined spiral section and a vertical section located at the bottom of the inclined spiral section. The two sealing gates are linked and their rotation directions are always opposite to each other.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In the solution of this utility model: In this device, the mechanical parts to be tested are picked up and placed from the back of the protective cover. A whole piece of transparent tempered glass panel is embedded and fixed in front of the protective cover, which makes it easy to clearly observe the state changes of the mechanical parts under high pressure. Furthermore, the rotation of the bidirectional lead screw controlled by the servo motor can control the two movable rods to drive the two clamping rods to move synchronously in opposite directions, which makes it easy to center and position the parts placed between the two clamping rods, so that the mechanical parts are located directly below the pressure block, which facilitates pressure application and quality inspection. When the hydraulic rod is activated to control the pressure block to move vertically downward, the two horizontal columns fixed on the upper outer wall of the pressure block can respectively squeeze the inclined spiral section of the guide groove on the surface of the two sealing gates. This allows the two sealing gates to rotate synchronously around the fixed tube in a direction that moves closer to each other. When the two sealing gates touch, the ends of the horizontal columns are exactly at the top of the vertical section of the guide groove. Subsequently, when the pressure block moves vertically downward, the sealing gates can be in a stable closed state. The closure of the two sealing gates allows the pressure testing process to be carried out within a closed protective cover. When parts break under high pressure, debris can be prevented from flying, making the testing work safer. Attached Figure Description

[0015] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings: like Figure 1-6As shown, the mechanical parts quality inspection device of this utility model includes a workbench 1, a servo motor 4, a hydraulic rod 9, a pressure sensor 10, a controller 13, and a pressure data display 14. A protective cover 2 is fixedly installed on the upper surface of the workbench 1. A servo motor 4 for driving a clamping assembly 6 is fixedly installed on the right side wall of the workbench 1. The clamping assembly 6 is located in the middle of the workbench 1 and inside the protective cover 2. A sealing assembly 7 for enhanced protection is installed on the inner rear end of the protective cover 2. A fixing tube 8 is fixedly installed at the center of the inner wall of the top of the protective cover 2. A hydraulic rod 9 is fixedly installed at the center of the top of the protective cover 2. A pressure block 11 is fixedly connected to the telescopic end of the hydraulic rod 9 through the pressure sensor 10. A horizontal column 12 for driving the sealing assembly 7 is symmetrically fixed on the outer wall of the upper end of the pressure block 11. A controller 13 and a pressure data display 14 are fixedly installed at the top of the protective cover 2. The controller 13 and the pressure data display 14 are located on both sides of the hydraulic rod 9, respectively.

[0016] Based on the above structure, a reinforced glass panel 3 is embedded and fixed at the front end of the protective cover 2. The reinforced glass panel 3 is transparent, and the interior of the workbench 1 is symmetrically provided with sliding grooves 5.

[0017] In this embodiment, a transparent reinforced glass panel 3 is used to facilitate clear observation of the state changes of mechanical parts under high pressure.

[0018] Based on the above structure, the clamping assembly 6 includes a bidirectional lead screw 61, a movable rod 62, and a clamping rod 63. The bidirectional lead screw 61 is rotatably mounted in the middle of the worktable 1 and its right end is fixedly connected to the output shaft of the servo motor 4. The bottom of the vertical sections of the two movable rods 62 are engaged and slidably located in the slide groove 5 and threadedly sleeved on the outside of the threaded section of the bidirectional lead screw 61. The horizontal sections of the two movable rods 62 are fixed with clamping rods 63 at their respective ends that are close to each other.

[0019] Based on the above structure, the two reverse threaded sections on the left and right sides of the bidirectional lead screw 61 are located within the range of the two sliding grooves 5, respectively.

[0020] In this embodiment, the servo motor 4 controls the rotation of the bidirectional lead screw 61, which in turn controls the two movable rods 62 to drive the two clamping rods 63 to move synchronously in opposite directions. This facilitates the centered clamping and positioning of the parts, placing the mechanical parts directly below the pressure block 11 for easy pressure application and quality inspection.

[0021] Based on the above structure, the sealing component 7 includes mounting rings 71, brackets 72 and sealing doors 73. Both mounting rings 71 are bearing sleeved on the outside of the fixed tube 8 and are arranged in the vertical direction. The brackets 72 are symmetrically fixed on the outer walls of the two mounting rings 71 in a staggered manner. The other ends of the two brackets 72 are respectively fixedly connected to the two sealing doors 73. The two sealing doors 73 are respectively movably located on the inner sides of the left and right ends of the protective cover 2, and the centers of the three coincide with each other.

[0022] Based on the above structure, when the two sealing doors 73 are closed, they form a closed structure with the protective cover 2. One side of the two sealing doors 73 slides against the inner wall of the protective cover 2, and the other side surface of the two sealing doors 73 is provided with guide grooves 74.

[0023] Based on the above structure, the ends of the two horizontal columns 12 away from the pressure block 11 are respectively guided to slide in the guide grooves 74 located on the surfaces of the two sealing gates 73. The guide grooves 74 include an inclined spiral section and a vertical section located at the bottom of the inclined spiral section. The two sealing gates 73 are linked together and their rotation directions are always opposite to each other.

[0024] In this embodiment, when the pressure block 11 moves vertically downward, the two horizontal columns 12 can respectively squeeze the inclined spiral section of the guide groove 74 on the surface of the two sealing gates 73, so that the two sealing gates 73 can rotate synchronously and move closer to each other. The closing of the two sealing gates 73 can make the pressure test process take place in the closed protective cover 2, which can avoid the splashing of debris and make the test work safer.

[0025] The working principle of this utility model is as follows: In use, first place the part to be inspected between the two clamping rods 63, then start the servo motor 4 to control the bidirectional lead screw 61 to rotate, so that the two movable rods 62 drive the two clamping rods 63 to move synchronously in the direction of mutual approach, so as to facilitate the centering and positioning of the part to be inspected, and so that the mechanical part is located directly below the pressure block 11. Then, the hydraulic rod 9 is activated to control the pressure block 11 to move vertically downward. At this time, the two horizontal columns 12 fixed on the upper outer wall of the pressure block 11 can respectively squeeze the inclined spiral section of the guide groove 74 on the surface of the two sealing gates 73, so that the two sealing gates 73 can rotate synchronously around the fixed tube 8 and move closer to each other. When the two sealing gates 73 touch, the end of the horizontal column 12 is exactly at the top of the vertical section of the guide groove 74. Then, when the pressure block 11 moves vertically downward, the sealing gates 73 can be in a stable closed state. The closure of the two sealing gates 73 can completely seal the protective cover 2, so that the pressure test process can be carried out in a closed environment. When the parts are broken under high pressure, the debris can be prevented from flying, and the safety of the test work is higher. Once the pressure block 11 moves down and contacts the mechanical parts, pressure testing of the mechanical parts can begin, and the pressure data can be fed back to the pressure data display 14 through the pressure sensor 10, making it convenient for the testing personnel to obtain and record the data. It should be noted that this device is powered by an external power source. The circuit layout and specific operating principle between the servo motor 4, hydraulic rod 9, pressure sensor 10, pressure data display 14 and controller 13 are all mature existing technologies and are not the key innovations or improvements in this case, so they will not be described in detail.

[0026] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
